The insurance industry (property/casualty and life/health) is a key player in the capital markets, with $5.2 trillion in cash and invested assets in 2015, according to S&P Global Market Intelligence. Total P/C cash and invested assets were $1.5 trillion in 2015, according to S&P Global Market Intelligence. L/H cash and invested assets totaled $3.7 trillion in 2015. The majority of these assets were in bonds (62 percent of P/C assets and 74 percent of L/H assets).
Because their losses are more volatile than those in the life insurance sector, property/casualty insurers invest largely in high-quality liquid securities, which can be sold quickly to pay claims resulting from a major hurricane, earthquake or man-made disaster such as a terrorist attack. Life insurers, whose benefit payments are more predictable, invest more heavily in corporate stocks and corporate and foreign bonds.
Insurance companies invest the premiums they collect in state and local municipal bonds, helping to fund the building of roads, schools and other public projects. They provide businesses with capital for research, expansions and other ventures through their investments in corporate equities and bonds. In 2015 alone, property/casualty insurers’ holdings in municipal bonds totaled $330 billion, according to the Federal Reserve.
